Similar letters of reference indicate corresponding parts.

The treadle A is mounted adjustably on a frame, A, capable of supportingit in the same relative position to either side of the table, so that itmay be changed from side to side, or to one end, as mayfoe -above therod. The treadle is also provided with `a semicirculzu. recess, fittingand oscillating on it.

The treadle is jointed to a lever, A, pivoted at 'A7,

and connected to the lower end of a connecting-rod, A, at A".

This rod A9 isconnected to a crank-shaft, Al, whereon is mounted afriction driving-wheel, All.

The shaft A1 is mounted on a frame, B, hinged at Bl to the side of theframe, and connected at the other end, on the opposite side of themachine, to a bar, B2, capable of rising and falling, and arranged abovea cam-dogB3, arranged on an axle, and provided with a handle for turningit, to raise or lower it, and above'A tlie'frame may be placed a spring,154, as seen in de tailin fig. 7, Sheet 1I of drawings, for pressing itdown.

The cam-dog is suspended by a hanger, B, from a bar, B6, fixed to theside of the frame, and the spring Bt, .when used, is arranged .underthis bar.

By turning this camdog into the position represented in iig. 7,'thefiahe B will be raised, carrying the wheel A up into contact with thefriction-wheel B7, on the crank-shaft B", arranged under the table,parallel with the needle-arm support,- and in the bearings B9 and B1".

This wheel Bl clutches with a ratchet-clutch, B, connected to the shaft,so as to impart rotary motion to it, but capable of sliding on ittoandfrom the wheel,

and provided with a spring, B1", to kecp it up against the clutch on thewheel.

This arrangement -is provided, so that if the drivin g'' wheel is turnedthe wrong way, the clutches will slip,

' and will not turn the crank-shaft.

Bla is a balance-wheel ou a crank-shaft, and B1* a friction-brake lever,pivoted at Bl, 'and provided with a rod, B16, rising up to the underside of the table, through which a iinger-stnd, B", with a socket in thebottom for the reception ofthe upper end of the rod B1, works, so thatthe operator may bring the brake into contact with the wheel at anytime, by pressing down thereon. y

This connection with the rod B is made to admit of raising the table,which is hinged at one side when required.

A jointed brace, B1, and sleeve, Bl, are provided for holding the tablewhen raised up. lhe ends of the jointed brace lap at the joint, andassume the saine line when the table is raised up, so that the sleeveslides on the lapped ends, and holds them from turn ing back.

The crank c of the shaft B is connected, by a connectingrod, el, with adiamondshaped plate, e, mounted onA a rock-shaft, c, and aconnecting-rod, c, connects this plate with the needle-arm o". 4

The connection of the rod c4 with 'the wrist-pin of the plate o2 is madeby means of a double joint, so arranged that the rod may haveoscillation in directions Vperpendicular to each other.

The needle-arm o2 works in a hollow needle-arm u-pport, c6, and isprovided at one, or it may be both ides of its point c7, with springsc", which have the tfect to prevent any pounding or jarring in arrestinghe motion ofthe needle-arm at the end of eachmovenent, which mightotherwise be the case, owing to he particul-ar arrangement of theoscillating plate c, ,nd the connections therewith.

c9 .represents the vibrating thread-tension spring, ivoted to theneedle-arm support at ci", and connected o the needle-arm by' the linkou. The end projects hrough the slot in the end of the needle-armsupport, ,nd is provided with a guide-eye, 0'2.

c13 is a spring, which may or may not be used, but ntended moreespecially for use when the link c is ivoted, as shown at 0M.

The shuttle-carrier D is a curved arm, forked at the xpperend, and ttcdat the lower end loosely7 on the JXle D1. It is worked by a crank, ])2,in the shaft B, .nd a connecting-rod, D. rlhe latter is made in' twoqual parts or halves, and fastened together by a sin- ;le screw. Thisconstruction allows the same to be piickly attached and removed.

D4 is the shuttle, which is supported with it's open ace, as seen iniig. 5, against the plate D5, by the forks )G of the arm D, so that thethread of the needle )asses between the said forks and the back of the;huttle.

rlhe lface of the plate D5 is provided with a vertical groove for theneedle opening to the face of the shut- ,le, vas shown in lig. 4, at D7,and in iig. 1, so that the oops from the needle project out of thesaidrecess )eyond the point of the shuttle.

The tension for the shuttle-threads is produced by t spring,'Df, bearingou the end D9 of the bobbin, and tdjusted by a set-screw, Dl, passingthrough the up- Jer side ofthe shuttle, and guarded, so as not to catchahe thread, by curved wire guard, D11; This screw maybe reached, foradjusting it, by a screw-drivel', `hrough the slot in the table, covered`by a slide, D12.

E is the feed-shoe. It is mounted on a vertical bar, iil, supported onits carrier, E2, so as to slide up or .lown thereon,` for adjustment asto height. It is dottedat Il, and slides on apin, E". It is supportedvertically ony a two-leaved spring, E5, pivoted at E6 to the 4carrierE2, and'a'rranged to bear the lower leaf, on t cam, FF, on the shaft D.

The upper leaf, to which the said vertical plate is :lirectl y connectedat its lower end, is supported above the lower one by anadjusting-screw, E", screwed through the upper leaf, and ou to the lowerone. By turning this screw one way or the other, the feed-dog may beadjusted higher or lower.

The carrier E2-is curved, from a point alittle below the set-screw E4,to the left, around the cam-shaft, as learly shown-in fig. '3, to theshaft D1, directly below. the saidcam-shaft. Here it is joined to acurved arm, F, projecting at equal distances from the said shaft, andprovided with notches F1 in the ends.

'A In front of this carrier is an inverted. V-shaped frame, F2, pivotedat F3 to a vertically-sliding bar, F, working up anddown on the bracketF5, and this bar is confined to the said bracket by a pin, F6,projecting through a slot in the bracket.

This sliding bar Fi comes in contact, at its foot,` with eccentric camFl; also, on the shaft B2, which throws simultaneously with the'cam E".

The lower ends of the arms of the frame F2 are connected by a curvedbar, F, provided with a'stud, F2, projecting through the bottom F10 ofthe case.

rlhe arms F2 are provided, a short distance above the bar F, withstud-pins H, permanently attached, and projecting from each side. Ontherear side these pins have heads, standing about the distance of thethickness of the bar Ffrom the arms F2.

este@ On the front side of these arms F? is a spring, Hl, fixed to theshaft D1, and projecting each way from the shaft a little further thanthe arm F. Each end is bent into the V-forni, shown at H2, and pressesupon thefront projections of one of the stud-pins H.

By means of this frame, the slide Fi, cam lli, and a bent adjlisting-arm Hf H4, pivoted to the under side lof the table at H5, andprovided with au adjustingscrew, HT, the--feedshoe is operated to feedin either direction, and the amount of feed adjusted as required, in thefollowing way The inverted V-shaped frame F2 may be moved on the axis FJso as to bring either ofthe pins ll into its respective notch on the endof the plate F, where it is held by the bent V-shaped ends of the springH1, which springs over the pin, the other pin at the same time esca-ping from it-s notchand from' the spring, when that side so engaged withthe arm F, (which, as shown in the drawings, fig. 3, in the right side,)willon being raised by the cam FT, and slide F4, raise that end ofthecurved bai F, oscillating it on' the axis D, throwing the feed-shoe tothe left. rlhe said shoe is also raised at the same time. to bring itinto contact with the cloth, by its cam '4" and slide El.

' If it be required to feed inthe opposite direct-ion, the invert'edV-shaped frame F2 is moved to the right, to disengage the pin attheright with the bars F2, and engage the other pin at the other end; then,when the said frame is raised, the shoe will be moved to feed to theright.

'lhe amount of the movementofthe feed-sboe is governed by the bent armH3 H, the part H3 of which takes under the stud-pin Fs, and arrests itin' the downward movement a greater or less distance from the cam F7,which correspondingly limits the oscillation of the bar F and the throwof the feed-arm E2.

The height of the feed-shoe, or the vertical movement thereof, is notdependent on the movement of the arm F.

The presser I slides in avertical slot in the head of the needle-armsupport, and is provided with a rod, 11, and passing through a holeabove the same to the top, where a square socket, I2, is formed.

I is a square finger-piece attached to the said rod, and fitting in saidsocket, and which is capable of turning when raised ont of the socket.`When so turned, it will rest on the top walls ofthe socket, and in thisway the presser is held out of acilion, when required, against theaction of the spiral spring l, in the socket which presses it down.

K is a tension-spring, provided with the verticallyprojecting ends,having points K1, for taking into the hole in the bobbin at each end,and having a rightal'id-le'ft threaded screw, K2, for moving thc saidpoints t0 or from 4each other. rlhe lower part of the springs isconnected at K:l to the needle-arm support, and the screw is` providedwith a disk, K", working in a grooved friction-block, K5, to prevent itfrom being turned by the jarring of the machine.

L represents a spooling-device, consisting of a stock projecting throughthe table, and supportinga groovcd pulley, L1, at the bottom, andanother, L2,. at the top. The upper pulley has a spindle, to which thespool L3 may be connected by one end, so as to be turned by it, theother end being supported in an arm, L, of the stock. A cord is fixed onthe grooved pulleys, and the lower one `is allowed to rest on thefrictionwheel Bl, which may be worked in the direct-ion to slip theclutch-Bll for spooling.

When the spinning-device, is not required for use, it may be raised outofcox'it-act with the wheels B7.
